Abstract
An apparatus and method for supplying emulsion ink to a printing plate on a printing press is disclosed. The apparatus includes an ink feed and recirculation system and associated control system to quickly and reliably form a high quality emulsion ink. The control system utilizes both feedback and feedforward control strategies. The recirculation of the emulsion ink ensures that the emulsion ink remains stable and makes it possible to reformulate the emulsion ink, if necessary, without waiting for the exhaustion of all of the emulsion ink that is in need of reformulation.
